Beyonce Opens Up About Her Miscarriage

Beyonce is speaking out about her miscarriage for the first time ever in her new HBO documentary Life Is But a Dream.

"About two years ago, I was pregnant for the first time," she says in a candid scene, according to Us Weekly. "And I heard the heartbeat, which was the most beautiful music I ever heard in my life. ... [but] I flew back to New York to get my check up -- and no heartbeat. Literally the week before I went to the doctor, everything was fine, but there was no heartbeat."

Beyonce's husband Jay-Z first opened up about the tragedy in his song Glory, written about their now one-year-old daughter Blue Ivy, but this is the first time Beyonce herself has discussed the heartbreaking loss.

"I picked out names," Beyonce recalls. "I envisioned what my child would look like . . . I was feeling very maternal."

It turns out Beyonce used the tragedy as inspiration for "the saddest song" she's ever written, though she doesn't name the song.

"I went into the studio and wrote the saddest song I've ever written in my life," she shares about the aftermath. "And it was the best form of therapy for me, because it was the saddest thing I've ever been through."
